Revolutionizing map use in Norwegian newspapers

Norway represents one of the countries with most newspapers and media outlets per person. One topic that has an everlasting interest is land registration data - or more commonly: Who bought which properties and what was the price. Land registration data has always been a public data set. Every citizen can request specific information on who has rights to which properties. Up until 1. January 2014 the digital version of this data set was monopolized by law to one vendor - obviously inhibiting innovation. Starting in 2014 - land registration data has been opened and is now accessible to everyone. Webatlas seized this opportunity and hired two summer interns. The task was fairly easy: "Revolutionize the way land registration data is used in local newspapers." After two hard-working months the resulting web application was used by a local newspaper with great results. The newspaper could finally showcase an interactive leaflet map displaying all real estate transactions in the area of interest. Behind the scenes the interns experienced a steep learning curve using PostGIS, GeoServer, Leaflet and a range of excellent plugins. Some of the more stable parts made it to the general use with an Open Source license on GitHub. Today. The solution is used in the majority of Norways newspapers - now showcasing more maps than ever! All made possible by two excellent interns, open data sets and well proven Open Source software components.

Live monitoring of ski tracks in Norway

This presentation is a complete walk-through of a system for live monitoring of ski tracks, built with open-source components. If ski track monitoring sounds odd to you, it is in principle the same as live monitoring a sweeping truck, snow-plough or any other road maintenance vehicle. The background for the system��s existence is a small, Norwegian town��s obsession with finding out where and when ski tracks were last prepared for them. A few man-hours, combined with the power of open source, has made it possible to create an affordable and efficient live tracking system. In this presentation, every aspect of the solution will be explained in full detail: The GPS tracking unit, the server and database components, and finally the web application that visualizes the data. Despite not being a revolutionary system, the concepts and experience drawn from this project can be useful to other developers who are starting off with open-source and geomatics. However, it may also be interesting to more weathered developers who would like to see a different approach to the problem of spatiotemporal data modelling with PostGIS. The open-source components that the presentation will touch on are the following: - Traccar - GPS trakcing server - PostgreSQL + PostGIS - Arduino - Apache2 + PHP + libpq
